v 4Claims. (c1. zsziyi This invention relates to a bank, and primarily to a bank of the pocket type,althoughit may be embodied in a largerban 1 It has for one object to'provide a simple slot guard or safety means; I

Another object is to provide a'slot guard so arranged that it notmerely prevents the withdrawal of coins through the'jslot, but tends to force or drivethe coins forcibly into the bank once'they have enteredthe slot. a a

Another object is to provide an end plate for a'bank'iupon which the slot'guard member is mounted, so that thetwo may-be considered as a unit and installedtogetherin a single opera-- tion afte'r having been assembled one upon an; other."

A still further object is to provide a slot guard I member and construction so arranged that the slot guard, although carried DI]. the topor-end of the bank, presses'against- 'a-side'w'all;

Other objects will appear from time to time throughout the specificationandclaims.

The invention isdllirstratedfhidror less diagrammatically in the "accompanying drawing, wherein: 1

Figur'e*3 is a plan view ofthe plate which carries-theslot'guard; f

' Figure 4 is a vertical section taken at line I 44ofFigure3.

Like parts are indicated by like characters throughout the specification and the drawing.

While the invention may be embodied in many bank constructions, in the particular form here shown the bank comprises three sections, I, 2, and 3, which may be relatively movable with respect to each other. The invention is not in any sense limited in its application to a multipart or telescopic bank. The section 3 is provided with a slot 4 which as shown in Figures 1 and 2 is inclined downwardly away from the top or end of the bank. The upper or outer end of the section 3 is closed by a plate 5, which is preferably a disc-like member, and beneath which or in contact with which is mounted a necessarythat the bank be cylindrical.

disc-like member 6 'upon which the slot guard construction is mounted, as will be described below.

The plates 5 and 6 are held in place against" a a shoulder formed by bending the upper. portion of the section 3 outwardly, and they are held in place against the shoulder by a flange 1, which is formed by bending downwardly, laterally, and inwardly the outer end of the member 3. u The plate 6 is formed to provide a 'pair 'ofj channel-like depressions 8; 8 which may terminate at perforationsS, 9, and which at their other ends run into orconn'ect with afn'otched I or cut-away portion l0.

The slot guard includes a spring which is provided with ends II, II, each of which projects through one'of the perforationsll and lies in oneof the depressions 8. Where they approach each other, the spring sections I l are curved to-provide' l loops I2 and arethen bent downwardly to'provide a loop [3, which extends as shown in Figures 2 and 4 below the 'rest of the-spring and 1 overlies the slot 4, The plate 6 may 'beprovided v with a raised portion, which as shown in Figures 2, 3, and 4;, overlies thejloops l2 of the spring and: assists in 'holdin'g the spring in place, This member l l for some purposes maybe omitted. I

K It will be realized that whereas I have described and shown a practical and operative em bodiment of my invention and thei 'method for carrying it out, nevertheless many changes may i be made in the size, shape; number and dispositionof parts and in the details and steps of such method without departing from the spirit of my invention. I therefore wish my description and drawing to betaken asin a 'broad s ense illustrative or diagrammatic, rath er than as limiting me to my precise showing" The user and operation of t e invention are as follows: i

In general the slot guardmechanism may be applied to a bank of any shapegand itis not" need not be applied to a telescopic bank, and the one shown is merely an example of a possible bank.

When the slot guard arrangement is applied a portion of vit rests yieldingly over or extends across a slot through which coins or tokens are to be inserted. When a coinis inserted it is pushed into the slot 4 and against the loop I3 of the spring and displaces the spring, moving it inwardly and upwardly, clockwise from the position of Figure 2, until the spring has been sufliciently displaced to permit a coin to enter. At the instant that the coin has been inserted suificiently to clear the inner edges of the slot, the loop I3 is no longer held upward, and is free to spring back toward its original position, and in doing so it forcibly drives the coin in-- wardly and downwardly into the bank. This is an important feature, because itprevents tam- Also it a,

by accident the coin may not slip under the edge of the member 13. a

In the assembly of the device the parts are made substantially as shown, with theflanga I not yet in the downward or'closedposition. The

disc 6 is given asuitable shape generally corresponding to the cross sectionpf; therbank and,

the spring which includes the arms H and the loops [2 and I3, is arranged in the positionshown.

When the spring hasbeenassembled'on the; disc 6, the latter movedinto place, against the: shoulder adjacent th upper end of; the member 3, If desired; a plate 5 may,be -,added.
